Problem running the DM368 PSP demo

Prodigy 245 points


Hi 

I am trying to get familiar with the DM368EVM by playing with the PSP example. following the instruction on

UG: DaVinci PSP Installation on DM36x EVM

    Topic:     Building and using the MT9P031 CMOS image sensor driver

         3. running the demo

when I boot up the DVM board and enter the command :

# /etc/init.d/load-module-rc restart

# ./capture_prev_rsz_onthe_fly_bayer_mew -i1 -m4 -h50

I got an error of : CMEM Error: allocPool: ioctl CMEM_IOCALLOC failed from pool 0: -1

 

Could someone tell me how to fix this in order to run the demo?

 

Thank you

 

Ming

    Hey,

    error indicates that either CMEM module is not loaded or it was not loaded with appropriate parameters.

    There are various posts on this forum which address the same issue. You can refer them.

    Thank you, Nagabhushana.

    I am sure the CMEM module is loaded.

    root@dm368-evm:~# lsmod

    Pool 0 free bufs:
    id 0: phys addr 0x1000
    root@dm368-evm:~#

    here is the parameters I find in the loadmodule-rc.sh

    load () {
        modprobe cmemk phys_start=0x83C00000 phys_end=0x88000000 allowOverlap=1 phys_start_1=0x00001000 phys_end_1=0x00008000 pools_1=1x28672 useHeapIfPoolUnavailable=1

    Do I need to define something like "pools_0=...." for the block_0 after phys_end=0x88000000.   ?

     

    On the other hand, the loop-back demo under the ti-dmai-apps folder is working, I can see the captured image on the monitor

     

    Regards

    I'm getting the same errors and the cmem has the same parameter any solution?
